nmarmcn Dunn Application. fled February 26, 1927. Serial No. 171,191.

My invention relates to dampers for a fireplace, and particularly to that form of damper, in which the damper plate is supported on a frame, and is operable from a 5 convenient place outside, and from the front of the fireplace masonry.

The object of my invention is to provide a damper structure which is easy to make, is economical in cost of manufacture; has no projecting parts which in transportation are liable to be broken; which may be arranged in its entiretyinto a convenient package for transportation at a low rate and at the same time provides a structure which is strong 16 and durable, easily installed, and dependable in operation. v

A further object of my invention is to provide a fireplace damper, operable from the outside of thefireplace from either the 20 center or one side, or from a convenient place within the fire lace.

Another and part cular object of my invention is to provide a shiftable guide post in the frame of my damper, this guide post to serve both as a stop for the damper plate, preventing the latter from becoming unseated by a too great movement thereof; the guide post also serving as the guide element for an operating chain attached to the damper plate.

p p I attain these and incidentalobjects of my invention in a fireplace damper comprising a frame consisting'of a basal web supporting a wall and provided with an interior flange on three sides, and said wall provided with spaced sockets one located at the middle of the frame, the other at one end thereof, and a post adapted to be inserted in either of said sockets. I provide a dampenplate pivotally supported at its ends within the said wall seating on said interior flange of the latter, and means for lifting and lowering the damper-plate. The said damperplate is provided with a longitudinal rib onits upper face including .a stop-lug registering'with said wall sockets to 'bear on the post settherein, and said post is provided with a guide-hole, and a thimble secured to said guide-post and registering with said guide-holeandextending through the brickfacing of the fireplace :for receivingan open ating-chain attached to said damper-plate.

My invention further embodies certain features hereinafter described with reference to the accompanying drawings.

In the drawings: Fig. 1 shows a perspective view of my fire place damper, the damper being shown separated from the frame;

shows a lever provided for operating the damper from outside .the fireplace;

Fig. 5 shows in a fragmentary transverse section an end view of the lever for openin and closing the damper;

'6 shows in a fragmentary longitudinal section the lever for opening and 010s ingdzhe damper; 1

ig. 7 shows a plan view of my damper installed in the t roat of a fireplace, the upper part of the masonry having been removed; and shows the damper vin a closed position, andanother operating means provided for opening and closing the damper shown, a portion of the damper and the masonry having 'Ibe'en'broken away;

F 8 shows a front elevation of a fire place,.a portion of the masonry being broken away disclosing the relative positions of the damper and frame within;

Fig. 9 shows a fragmentary section taken on the line 99 of Fig. '7 looking in the direction of the arrows and discloses the opening and closing means employed for operating the damper from outside the fireplace; and

Fig. 10 shows a fragmentary section similarly to Fig. '9 except that the damper plate is in an open position. r

My damper comprises a frame a formed in an elongated trapezoid comprising a basal web '6 provided with integral perpendicular walls 0 and aninwardly sloping wall 6%.

The walls and d are spaced from the edge of the basal web b and are in height approximately equal to the distance they are spaced from the edges of the basal web.

An interior fian ge h is formed at the base of the wall 0 and interior end flanges i are formed extending diagonally upward from the base of the wall 0 to the top of the wall 03. A transverse brace 0 is similarly formed at the center of the frame a to provide support for the damper plate and strengthen the frame.

Sockets m and m are provided in the longitudinal wall 0, at the center and one end respectively, and a removable post Z is provided adapted to lit into either of th sockets m or m and is formed with an cy Z at its end.

adapted to rest on the interior flanges ft and 2' and on the top of the wall cl forming a e, are adapted to seat in notches formed ii:

the interior corners of the frame formed by protrusions j and j.

The damper plate 6 is also proviued with upstanding lugs 39 of the central rib g and holes 7 and 1".

The damper plate 0 is formed with an rip-i standing longitudinal rib g which is highest at its center 11 and one end p, and is ported by a suitable angle iron 10. tight closure at all points. Pintles f and f provided on each end of the damper platl with fan-like corrugations 6.

A crank arm 7 which extends through the slot 3 is provided on the end of the pintle f and bears against the corrugations 6. The rank arm 7 is offset and extends downward nto the opening of the fireplace and may be perated conveniently from there.

As best shown in F i s. 4t and the front portion of the basal web will be left off as at ll in order not to interfere with the backing 8 for the tile facing 9 which may be sup- 1 claim: 1. A fireplace damper comprising, a frame 'fl consisting of a basal web supporting a wall, .said wall provided with a socket, a post adapted to be inserted in said socket, and a damper plate pivotally supported at its ends 9 and gon its outer edge within the said wall. correspondingly spaced as the portions and are provided with said wall provided with a socket, a post By providing two sockets m andm and a rdapted to be inserted in said socket, a dampost Z adapted to fit in either one, and cor-i per-plate pivotally supported at its ends responding lugs being operated from the center or the side of the front of the fireplace.

Referring now to Fig. 3, I show a modification of my damper in which the pintles f, 7' will be seated in the notches a cut in the walls 0. In this form of construction the damper plate and the pintles f and j will be formed somewhat larger.

In Figs. 7, 8 and 9 I show my damper adapted to be operated from the center. A chain '15 is fixed to the lug g and adapted to pass over and bear on the portion 32 of the web 9 and is then passed through a thimble a which is threaded into the hole Z in the post Z. A keyhole slot is provided in the outer end of the thimble a in which the links of chain may be engaged so that the damper may be set in any desired position, and the and g and also two raised portions of the ri g, I adapt my damper for" ,within the said wall, and means for lifting l consisting of a basal web supporting a wall,

said wall provided with a socket, a post adapted to be inserted in said socket, a damper-plate.p1votally supported at its ends within the said wall, means for lifting and lowering the damper-plate, and said damperplate provided with a stop-lug registering with said wall socket to bear on the post set therein.
